Manager Project Management at Capgemini
Very good performance and load testing capabilities
There are some compatibility issues with the load standpoint test. When we use the solution instead of Microsoft Edge, more scripting is required. The reports for structure point or test management could be more compatible with other tools. For example, when I create an application I sometimes cannot generate a report.

Cloud-based testing has simplified remote mobile validation and provides flexible device coverage
I was not impressed with how detailed their analytics and logs are from LambdaTest. The solution we were testing is being used because many of us are working from home. It was easy to implement because with a real phone, we have to bring a real phone to each person. Since three years ago, many employees have been working from home, so we were trying to find a solution for this challenge. We had no need to exploit the information for the analytics generated in the background. The purpose was simply to make it easy for our employees to access a phone. The downsides I noticed include that the pricing was very good, but the visual quality of the image sometimes suffers. The contrast on a real iPhone provides better contrast than with the cloud solution. The only aspect that was less favorable than on a real phone was the contrast of the color.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"The way it identifies elements is good."
"The most valuable aspects of the solution are the font, size, and interface."
"Has a very smooth process for launching and closing the application after execution."
"The object repository is the most valuable feature, as different elements can be identified and reutilized through the repository across other scripts, and the product has a very smooth process for launching and closing the application after execution."
"The performance and load testing are very good."
"Before using Telerik Test Studio, I was a manual tester, so it was my first automation tool, yet I felt very comfortable using it. I've used the record and play feature, and Telerik Test Studio was easy to use. The tool was easy to understand, even for a first-time user like me."
"Geolocation testing is as straightforward as ticking checkboxes of browsers, operating systems, and countries."
"It is a scalable solution."
"Stability-wise, I have not experienced any downtime or other performance issues."
"The technical support services are excellent."
"It’s good to see, now that we are using LambdaTest, we can run multiple tests on multiple VMs, saving us hours of testing time and the maintenance cost of local infrastructure."
"LambdaTest was handy and easy enough to save us a lot of time, effort, and money."
"HyperExecute adds significant speed to execution, enhancing the overall testing process."
"LambdaTest easily integrates with leading project management, bug tracking, and CI-CD tools like Jira, Asana, Jenkins, Circle CI, and more."
 

Cons

"Its UI is not very user-friendly and could be improved. For new users, it isn't easy."
"The first time I customized the solution, it was quite challenging."
"There are some compatibility issues with the load standpoint test."
"It can be improved by including a feature that allows multiple file types to be selected simultaneously."
"The charts need to be more detailed and customizable."
"I observed that the Excel and Word validation was quite challenging, which is an area for improvement in the tool. I also experienced minor difficulties with Telerik Test Studio, particularly in fetching elements in some scenarios when using C# for coding."
"We have not seen a return on investment yet."
"You cannot perform native-app testing, as they offer simulation for web testing only."
"I didn't like the solution's technical support and how they communicated and tried to fix the issues of customers like me."
"We get logged out of the devices if there is some inactivity."
"I've also had some issues with the speed of certain API calls and the rendering of data. For example, when I'm onboarding data, the process can be slow."
"The downsides I noticed include that the pricing was very good, but the visual quality of the image sometimes suffers."
"If possible to simulate the finger pinch, it would make it more realistic."
"It would be much easier for us to read the test if they provided dashboard analytics."
"Analytics could be better because as of now, it gives basic information on test status and build status."
